A data scientist is a professional who works with data to extract insights, knowledge and meaning from it. They use a range of skills from statistical analysis and machine learning to data visualisation and storytelling to make sense of complex data and communicate their findings to others.
The role of a data scientist involves working with large and complex data sets, identifying patterns and trends, and creating models to predict future outcomes or behaviours. They work with both structured and unstructured data from a variety of sources, such as social media, transactional data, and sensor data, among others.
